Styroboard XPS 20mm 600mm X 2400mm

Robust & resilient XPS for superior thermal performance.

Extruded polystyrene

The Styroboard XPS 20mm (600mm x 2400mm) is a high-performance extruded polystyrene (XPS) board offering exceptional thermal insulation and durability. Engineered for superior compressive strength and moisture resistance, this XPS board ensures consistent R-values, making it an ideal choice for wall cladding, flooring, roofing, and under slab insulation in both commercial and residential projects. Lightweight and easy to install, it delivers reliable energy efficiency and long-lasting protection.

Key Features:

• Size: 20mm thickness, 600mm x 2400mm dimensions for versatile application
• Superior Thermal Insulation: Maintains excellent R-values for energy efficiency
• High Compressive Strength: Robust and durable for multiple construction uses
• Moisture Resistant: Prevents water absorption for enhanced longevity
• Lightweight & Easy to Handle: Simplifies installation for faster project completion
• Versatile Applications: Suitable for wall cladding, flooring, roofing, and under slab insulation

Styroboard XPS by RSC has become the material of choice for home builders, specifiers, architects and engineers due to its high compressive strength and superior thermal performance.

While expanded polystyrene offers greater flexibility and versatility, extruded polystyrene provides higher long-term R-values and thermal performance. A resilient and robust construction material, Styroboard XPS can be used across a range of building and construction applications – both residential and commercial.

When insulation comes into contact with water it can have an adverse effect on its ability to thermally insulate; but when faced with extreme weather conditions, Styroboard XPS still preserves its thermal and physical properties thanks to its high-density cell structure, making it practically impervious to water.

Dimensionally stable, organically inert and moisture resistant, Styroboard XPS meets a number of key requirements in structural and civil engineering. With superior compressive strength and higher, long-term R-Values Styroboard XPS is suitable for use on floors subjected to engineered loads and constant traffic, as well as insulation for inverted roofs, rooftop gardens, parking decks and as commercial purlin roof spacers.

Fire Properties

All Styroboard XPS products are manufactured from a fire-retardant raw material and do not present as a fire hazard when correctly installed. Like other organic materials, polystyrene will burn when in contact with a flame, but it will self-extinguish when the fire source is removed.

Environmental Properties

Produced with no refrigerants and free from HCFCs, Styroboard XPS is a truly green building product. With Styroboard XPS you can limit external temperature influences, reduce internal temperature fluctuations, and in turn, reduce the need for mass air-conditioning and electricity consumption. Maintaining thermal consistency means less energy is consumed, which leads to fewer greenhouse emissions.
